Figure App.C.4.14. Marine debris estimates modeled along the mainland southern California coast based on debris measured by the National Marine Debris Monitoring Program. Marine debris was relatively constant across the last five years of this time series (1999-2007) and within historic levels. Data source: Ribic et al. 2012; Figure: K. Andrews/NOAA
Figure App.C.4.15. Variation over time in percentage of stations from winter CalCOFI cruises with plastic micro-debris. Micro-debris was present in more than 50 percent of samples at each time period. Figure: Gilfillan et al. 2009
Figure App.C.4.16. Spatial distribution, concentration, and characteristics of plastic micro-debris in net samples from the CalCOFI region from winter cruises in (A) 1984, (B) 1994, and (C) 2007. Open circles indicate no plastic debris detected and filled circle diameter are proportional to particle concentrations (number per cubic meter). There was no relationship between the numerical concentration of particles and distance from shore, the presumed source of the majority of debris. Figure: Gilfillan et al. 2009


Figure App.C.4.9. Rates of human-caused disturbance to seabird breeding and roosting sites were low on Santa Cruz Island (SC) compared to other sites across the south coast (SCSR), central coast (CCSR), and north central coast (NCCSR) study regions. Activities noted as causing disturbance at SC in 2012 to 2013 were human power boats, recreational fishing boats, recreational power boats, commercial fishing boats, airplanes, and helicopters. SD = San Diego, PV = Palos Verdes Peninsula, SB = Shell Beach, MD = Montaña de Oro, EB = Estero Bluffs, MO = Montara, PR = Point Reyes, BO = Bodega. Figure: Robinette et al. 2015
Figure App.C.4.10. Annual number of large whale entanglements reported (blue) and confirmed (red) along the U.S. West Coast. Reports of entanglements have increased in recent years. Factors contributing to this trend likely include an increasing overlap of whale activities (e.g., migrating, feeding) with human activities that have the potential to entangle whales (e.g., fishing, buoy installation) and an increase in on-the-water observers likely to report entangled individuals (e.g., whale watching, recreational boating). Confirmed entanglements from 2000 to 2015 of gray and humpback whales include 11 from Santa Barbara and two from Ventura counties. Figure: D. Lawson/NMFS WCRO PRD
Figure App.C.4.11. Co-occurrence score (risk) based on multi-year average whale density and fishing effort for 11 fisheries is shown for quarters three (Q3) and four (Q4) for blue (top), fin (middle), and humpback (bottom) whales. In Santa Barbara from July to December, there is an elevated risk area for multiple whale species with the California halibut/white seabass set gillnet, hagfish trap, rock crab trap, sablefish, spiny lobster trap, and spot prawn trap fisheries.
